The [W3C-INDEXEDDB-2] specification defines APIs for a database of records holding simple values and hierarchical objects. Each record consists of a key and some value. Records are accessed by key or by an indexed attribute. 1.1 Glossary MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as defined in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT. 1.2 References Links to a document in the Microsoft Open Specifications library point to the correct section in the most recently published version of the referenced document. However, because individual documents in the library are not updated at the same time, the section numbers in the documents may not match. You can confirm the correct section numbering by checking the Errata. 1.2.1 Normative References We conduct frequent surveys of the normative references to assure their continued availability. If you have any issue with finding a normative reference, please contact [email protected]. We will assist you in finding the relevant information.

Microsoft Edge Each browser version may implement multiple document rendering modes. The modes vary from one to another in support of the standard. The following table lists the document modes supported by each browser version. Browser Version Document Modes Supported Microsoft Edge EdgeHTML Mode For each variation presented in this document there is a list of the document modes and browser versions that exhibit the behavior described by the variation. All combinations of modes and versions that are not listed conform to the specification. For example, the following list for a variation indicates that the variation exists in three document modes in all browser
